these are garbage collector symbols, automatically generated by gengtype.
Perhaps the library/object file defining _gt_ggc_r_gt_darwin_c_h is not
being linked with?  The darwin build has had lots of modifications that I
don't understand, and probably this broke Fortran (no-one off linux ever
seems to build it, which is bad).  I suggest you search in the generated
object files and libraries to find where the symbol is defined.

Ciao,

Duncan.
